.ELEVATOR-IDRAG.

Be it known that}, Anonzo Tennis, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Elevator- Drags, of which the following is a specification', reference being had therein to the acconrhipanying drawing.

y invention relates to that class of "cross-conveyors or drags for elevators used to elevate grain and other materials to bins,

cars or other places,-and adapted to be swung into position behind the wagon to re ceive the grain from it.

The invention relates to certaln novel features of construction and arrangement of parts hereinafter fully disclosed and then v pointedout in the appended claims.

2.0 "ing-a practical embodiment of my invention In the accompanying drawings illustrat- Figure 1 is a side view of the front portion of an elevator with a receiving hopper or drag-exemplifying my invention and swung into position behind the wagon shown in position to, discharge its load into the hopper; Fig. 2 is a central long1tudinal sectional view through the associated .ends of the elevator and hopper; Fig. 3 isia vertical longitudinal view in detail through the outer or free end ofthe hopper; Fig. tis a horizontal longitudinal sectional View on the,

line 4-4 of Fig. 3-;Fi g. "5 is a vertical cross sectional v1ew ,on-'l?ne 5-5 of F 1g. 3, and Fig. 6 1s iL-VGItlCztl cross sectional view on line -66 of Fig. l. I The elevator comprises a tubular mast 20 having ag/ endless-conveyer composed of buckets or flights 21 connected by a suitably driven chain 22, and provided with a boot V at'its intake end, the elevator being mountedlon 'itsbase or support by a swinging frame 24 and raised or loocred by any suitable means preferably tho-1v -discloseddn my co-pending application lilml .\T'arch 2525969;- Serial'No. 485,640, of which the present application is a division. The! boot 48 is rovided "with. a shaft 4=9.provided witli a sprocket wheel 50 in'th boot. to drive the conveyer and at one ent with a sprocket wheel 51"and at the other, with a sprocket wheel '53} driven by a'sprocket, chain 54 from a driving shaft 55.

of the boot-cover by a suitable receiving hopper 69 one end of which is supported in adjustable and detachable relation to the boot, and with such arrangement that. the drive of the conve er in the mast also drives the drive shaft '3 of the conveyer in the hopper when the latter is inposition on the boot, these parts being the same .as and on filed Aprihm), 1912 The grain is fed into the. inlet in the top forming part of the invention claimed in my aforesaid application. The hopper is provided at its free end with a skidding leg or support 7 9 which is rounded on-both sides to allow'the same to slide or skid over the ground when the hopper is swung in either direction and which may be folded down upon the bottom of the hopper when the latter is detached as for transportation or storage. The shaft '78 in the hopper is provided with a sprocket wheel 85 to drive the hopper-conveyer which moves in the direction of the arrow in Fig. 2. l v

The hopper may be of any suitable form and construction and in the present embodiment consists of a rectangular metal body having sides 86, rear end Y87, and a flat bottom 88. The hopper also provides bearings sprocket 90 for the conveyer. The conveyor is of" any suitable form, and in the embodiment shown the flights 91 m connected by a sprocket chain 92 cooperating with the sprocket wheels 85 and 90, which are so located with reference to the bottom that the flights sweep over the upper face thereof in their travel between the shafts, the flights being substantially rectangular in contour and extending across the hopper. The hopper is provided with a horizontal shelf or partition 93 extending across the hopper for substantially its length inline with the up per portions of the sprockets 85 and 90 and cut away at its ends to receive the same. The flights 91 pass along this shelf 93 upon [which the grainis dumped or deposited and for a front shaft 89 having the usual feed-th' grain into the boot-inlet in the di-' rection of travel of the flights 21 there-- through so that the flights pass down upon the-grain in the boot.

The front shaft 89 of the hopper conveyer is supported preferably in a movable end section substantially as slvcwvn in Figs. 4, 5 and in hese figures the reference numeral 94 indicates an opposite pair of side plates resting against the inner faces of the that the end section acts as a tightener for the hopper conveyer by reason of its adjustability in the hopper. Theend section also provides a return-throat for any grain that may have lodged upon the conveyer bottom 88. For this purpose the side pieces 94 also support a curvedcross piece or deflector 98 extending across the width of the hopper in front of the sprocket 90 and curved substantially upon a segment of the circle described by the outer ends of the flights as they pass about the sprocket. This curved wall or deflector is flush with the bottom 88 and extends to a point substantially over the shelf 93, thereby furnishing'a return throat so that any grain lodged upon the ower floor of the hopper is carried by the flights back up through the throat to the upper floor 93 of the hopper in position to be acted upon by the flights as they move toward the exit 7 0.

The hopper is provided with. a reversible guide trough upon one side 'to' receive the rear end of the wagonbody when the latter is dumping the grain. This trough is shown in Figs'l and 6 and consists of an opposite pair of end walls 99 connected by a rear Wall 100. The end walls are considerably wider than the cross-section of the hopper 69 in order to form a larger receiving area for the grain as it flows from the wagon, and the bottom. of the troughis flared being composed of the oppositely sloping Walls 101 extending inwardly toward each other and leaving a central opening of substantially the same width as the hopper, the sloping bottom walls being provided with flanges 102 adapted to set within the sides 86 of the hopper as shown in Fig. 6. The trough is preferably adapted to overhang and extend beyond the front end of the hopper as shown in Figs. 2 and 3, and is there provided with a supplemental inclined bottom piece 103 extending from the front end 99 to a point within the hopper. The opposite end of the trough is provided with a trimmer 10% adapted to be raised and lowered andheld in position by a set screw 105, the lower edge of the trimmer being rounded so as not to interfere with the passage of the grain. The trough may be reversed upon thellopper so as to accommodate a wagon driving into position from being adapted to set within the hopper in either position of the trough. f

When the elevator is used the mast is swung to-inclined position to deliver the grain at the desired point, and the receiving hopper is arranged to discharge into the boot as the grain is dumped therein. The shaft 49 is suitably driven to move the conveyer in the mast to elevate the grain from the boot to the upper discharge end.

path of the loaded wagon to allow the latter to drive to position and then swung to position in rear of the-wagon to catch the grain from the wagon end-gate and feed it to the boot.
